　　 Vacuum zipper bag

　　1、 There is a problem with the transparency of the vacuum bag substrate itself, crystal spots on the surface of the inner substrate, shark skin and other quality problems, or the ink contaminates the packaging bag during printing.

　　2、 The color of the adhesive is too dark. Because it requires high transparency, try to avoid using dark yellow and dark red adhesives, and make them colorless.

　　3、 Improper glue preparation procedure will lead to insufficient and uniform mixing of main agent and curing agent. "Glue particles" may occur.

　　4、 Appearance defects, such as glue spots

　　5、 The temperature of drying tunnel is improper. If the temperature is too high at the beginning of entering the drying tunnel, the concentration of glue solution on the surface layer of the packaging bag will increase, and the surface will be skinned and uneven.

　　A good product should be finely crafted. The food packaging bags, aluminum foil bags and cooking bags produced by our company meet the food requirements and have guaranteed quality.
